Parameter |
Description |
|---|---|
StartPdoCopy |
Start of copying the Pdo data. |
EndPdoCopy |
End of copying the Pdo data. |
StartPdoDataSet1 |
Start of prepare the Pdo data set 1. |
EndPdoDataSet1 |
End of prepare the Pdo data set 1. |
StartPdoDataSet2 |
Start of prepare the Pdo data set 2. |
EndPdoDataSet2 |
End of prepare the Pdo data set 2. |
Count |
The amount of occurrences of this exceptions. To prevent generating too many exceptions only one exception is generated representing potentially many occurrences. |
Description¶
The PDO data is already copied while DMA copies are still busy. This might result in resending data of the previous sample. This is typically visible as jittering data in acquisition. Root-cause might be: 1) A calculate phase overload occurs, 2) Calculate phase budget is too large, 3) Sync1 is not calculated correctly by the master.
